A dental printer is a consumable engine: the LCD is the cartridge. Budget for it and the machine runs for years.
The real wear items
| Part | Life | Signal to replace |
|---|---|---|
| LCD panel | 1,000–2,000 h | Dim edges, under-cure |
| FEP film | Every 2–4 L | Scratches, leaks |
| Build plate | Years | Loss of adhesion |
Extend it
- Wipe the LCD after every 5 prints; dust scatters light.
- Keep resin at 23–25 °C; cold resin needs more exposure.
- Replace FEP at the first haze, not the first leak.
The AI Printing Series tracks LCD hours on-screen so you replace before failure.
The parts that wear
| Part | Replace |
|---|---|
| FEP / nFEP film | Every 1–2 L resin |
| LCD screen | 1,000–2,000 h |
| Wiper blade | Yearly |
Daily and monthly
- Daily: wipe the build plate with IPA; a greasy plate delaminates the first layers.
- Monthly: dust the fan; heat shortens screen life.
- Quarterly: re-level the plate; a 0.1 mm tilt wrecks adhesion.
